Description

This error indicates that an internal buffer or memory limit was exceeded during an SAP S/4HANA operation. It often occurs when the system attempts to process an exceptionally large volume of data or execute a highly complex task, leading to a temporary exhaustion of allocated resources for that specific process.

💬

Error Message

ERR_TEXT_COMMON_OVERFLOW_ERROR

🔍

Known Causes

3 known causes

⚠️

Large Data Set Processing

Executing reports or transactions that process an unusually high volume of data can exceed internal buffer limits within SAP S/4HANA.

⚠️

Complex System Operations

Intricate calculations, custom ABAP code, or complex system logic might demand more internal resources than are available for a specific process.

⚠️

Underlying Software Issue

In some cases, the error may point to a specific software bug or an unexpected limitation in the SAP S/4HANA core system or a custom development.

Solutions

3 solutions available

1. Investigate and Resolve Data Type Mismatches in Custom Code advanced

Identify and correct data type definitions in ABAP programs that are causing overflow.

1

Identify the ABAP program and specific data objects causing the overflow. This often requires debugging the ABAP code during the transaction that triggers the error. Use transaction SE80 or SE38 to access ABAP Workbench.

2

During debugging (using /h), set breakpoints at points where numerical or string data is being processed. Examine the values and data types of variables when the error occurs. Pay close attention to fields declared as INT1, INT2, INT4, or PACKED, and large strings.

3

If a field is consistently exceeding its defined limit (e.g., an integer field trying to store a value larger than 2,147,483,647 for INT4, or a string field exceeding its maximum length), modify the data type definition in the ABAP code. For numerical overflows, consider using larger data types like INT8 or DECFLOAT. For string overflows, increase the length of the character type field.

Example of modifying data type in ABAP:

* Before:
DATA lv_counter TYPE i.

* After:
DATA lv_counter TYPE i8.  " Or DECFLOAT for very large numbers

4

Recompile and activate the modified ABAP program. Test the transaction again to ensure the error is resolved.

2. Analyze and Optimize SAP Standard Objects with High Data Volume medium

Examine large standard tables and views that might be contributing to overflow conditions during reporting or processing.

1

Identify SAP standard tables or views that are frequently accessed or are known to store large volumes of data relevant to the transaction causing the error. Use transaction SE11 to browse table structures.

2

Check the data types of the fields within these tables. While direct modification of SAP standard objects is generally discouraged, understanding the data types is crucial. For instance, if a standard table uses INT4 and a specific business scenario generates values exceeding this, it might indicate a need for SAP Notes or a more complex solution.

3

If the overflow is occurring during a reporting scenario (e.g., using SAP Fiori apps or BW/4HANA queries that pull data from S/4HANA), review the query definition. Ensure that aggregations and calculations within the query are not leading to intermediate results that exceed data type limits. Consider using appropriate data types in the query designer or the underlying data models.

4

For scenarios involving large data transfers or aggregations, investigate SAP Notes related to performance and data handling for the specific business process or module. SAP often releases corrections for such issues.

3. Review and Adjust Application Server Configuration for Memory medium

Ensure the SAP application server has sufficient memory allocated to handle data processing, especially for memory-intensive operations.

1

Access the SAP system profile parameters using transaction RZ10.

2

Review parameters related to memory management, such as `ztta/roll_area` (maximum roll area per dialog process), `abap/heap_area_dia` (maximum heap area per dialog process), and `abap/heap_area_non_dia` (maximum heap area per non-dialog process).

3

If these parameters are set too low, and the system is experiencing frequent overflows during large data processing or complex calculations, consider increasing them. However, do this cautiously and in consultation with SAP Basis experts, as excessively high values can impact system stability.

Example of parameter modification in RZ10:

Parameter Name: ztta/roll_area
New Value: 20000000 (e.g., 20MB, adjust based on system needs and analysis)

4

After changing parameters, restart the SAP application server instances for the changes to take effect.
